BSHC expertise includes a wide range of activities executed by highly skilled and experienced personnel, well trained to interact with customers and aiming at accurate and optimal solutions. The scope of the performed scientific and applied research considerably covers such fields as ship resistance and propulsion, cavitation, maneuverability, seakeeping, ocean engineering, coastal and river engineering, as well as aerodynamics. The rich variety of experimental facilities and instrumentation as well as the expertise gained in years of operation are prerequisites for successful implementation of investigation on various non-standard objects and processes related to marine technology, water transport and reclamation of natural resources.

1- SHIP HYDRODINAMICS
* Investigations of the powering performance, seakeeping and manoeuvrability of seagoing or river ships and barge trains as well as small
boats and yachts in laboratory and in full scale conditions;
* Hydrodynamic design and optimization of the ship/trains hull forms, of ship propellers from the positions of the powering
performance/seakeeping/ manoeuvrability/cavitation/vibrations/noise, etc.
* Practical issues of ship operation such as trim optimization, application of power-saving devices, etc.

2- SHIP DYNAMICS AND OCEAN ENGINEERING
* Investigations on the behaviour of ships, floating platforms and sea structures when subjected to realistic operational conditions (waves,
currents, winds), including static and operational stability, forces and motions, wave loads, mooring systems, etc
* Development and implementation of on-board operation control systems as well as emergency response
Systems;
* Theoretical and experimental investigations of sea/river ships disasters;
* Hydrodynamic model investigations of structures for utilizing seas/rivers energy;
* Theoretical and experimental investigations of the manoeuvrability of sea/river ships and barge trains;
* Utilization of training simulator for pushed trains navigation on danube river and the inner european
Water routes;
* Small boats and yachts performance in wind and wave conditions

3-COASTAL ENGINEERING
* Hydrodynamic model investigations: of the generation and spreading of wind generated waves and waves generated currents in the near
coast zone; of the waves impact on the coast and on the coastal engineering structures; of the sediments transport and of the sea bottom lay
change in the near coast zone;
* Hydrodynamic model investigations of the passing river ships/barge trains impact on the river banks/beds;
* Hydrodynamic model investigations of risk factors/floods on the lower danube river.

4 – AERODINAMICS
* Aerodynamic model investigations of ships/transport structures/floating platforms/ flying
apparatuses/city microregions/industrial buildings;
* Determination of the metrological characteristics of measuring devices of the wind/air currents/flows parameters;
* Aerodynamic model investigations of facilities/devices for wind energy utilization.

5- WATER TRANSPORT EFFECTIVENESS
* Investigations of the sea/river transport effectiveness;
* Hydrodynamic model investigations of new generations sea/river ships/barge trains;
* Development of intermodal transport schemes for the danube-main-rhine waterway.

6-MARINE ENGEINEERING SOFTWARE
* Numerical methods implementation in the fluid dynamics (CFD);
* Implementation of computer simulation of processes in the hydro- and aerodynamics;
* Development of information and operation control on – board computer systems;
* Development of data acquisition and processing systems for the experimental facilities.

7 – MODEL MANUFACTURE
* CAD/CAM of models of ships, platforms, screw propellers, nozzles, podded propellers, water jets, etc.,
intended for hydro/aerodynamic model investigations.

8– DEVELOPMENT & MANUFACTURE OF EXPERIMENTAL EQUIPMENT

9- TECHNOLOGIES FOR THE NEEDS OF SECURITY AND DEFENS
* Design and investigations of terroristic actions averting devices in Bulgarian territorial waters;
* Multi directionaL theoretical and experimental investigations of high-performance naval ships in cooperation with NATO and US Navy.

10- PRACTICAL & OPERATIONAL INVESTIGATIONS
* Calculations and development of class required ship standard documentation such as Trim&Stability
* Booklets, Damage Stability Booklets, Cargo Loading Manuals, Tonnage calculations, Freeboard calculations,
* Ballast water management booklets, etc.
* Performance of full scale inclining tests
* Assessment of weather factors on speed loss at sea
* Trim Optimization
* Variety of practical problems arising in ship and offshore operation, under customer request (might be related with design and production of special testing appliances and instrumentation)
